Pipe cleaning device



Nov. 29, 1932. s. o. MATTISON PIPE CLEANING DEVICE Filed June 25. 1931 Patented Nov. 29, 1932 UNITED STATES SIGURD o. MArrIsoN, or eotmx, Wisconsin PIPE CLEANING DEVICE Application filed June 25,

This invention relates-to an improved pipe cleaning device.

One of the objects of the present invention is the provision of a simple and inexpensive device which can be carried about in the pocket of a smoker and can be readily applied to the usual well known filling valve on air pressure lines, particularly that type of valve which is attached to pressure lines at filling stations for filling pneumatic tires with air under pressure, and the device is so arranged that when connected up with this type of valve, air under pressure can be readily passed through a smoking pipe'to clean the same of any obstructions therein without the necessity of blowing the moisture ladened breath of the user through it.

Another object of the present invention is the provision of a pipe cleaning device in the form of a yieldable ball or plug-like member adapted to be inserted into the mouth of a pipe bowl, and is provided with a conduit adapted to be connected to air under pressure whereby the air under pressure will be forced into the bowl and through the stem of the pipe, the yieldable plug-like member preventing the escape of air at the mouth of the bowl so that all of the air pressure will be directed through the pipe bowl and through the stem thereof to remove moisture and other particles which may have accumulated in the stem.

With the above and other objects in view, the invention consists in the novel features of construction, the combination and arrangements of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawing:

Figure 1 illustrates in side elevation a smoking pipe in diagrammatic form, illustrating the application of my invention with the device shown in vertical section;

Figure 2 is a top plan view; and,

Figure 3 is a side elevation illustrating a modified form of the invention with parts thereof broken away and illustrated in cross section. a a

Referring more particularly to the drawing, 1 indicates the usual type of pipe bowl with a stem 2 attached thereto. In a great 19312- Serial no. 546 802.

many instances, it is the practice of a user of a smoking pipe to blow through the stem for removing particles of tobacco, moisture and the like, which may have accumulated therein and this practice usually carries into the pipe stem moisture from the mouth of a user and is a very objectional practice. p

My improved device includes a ball-like member 3 which is of suiiicient size to fit the ordinary type of pipe bowl and to be snugly fitted into A, the mouth, of the bowl as illustrated in Figure 1. Thi's'ba-ll is preferably constructed of comparatively soft rubber so that witha slight pressure applied-thereto, it will seal the mouth of a pipe bowl. EX- tending transversely through the ball 3 is a tube 4 having an enlarged nipple portion 5* at theouter end thereof which is adapted to be fitted-into-the ordinary type of check valve 6 which is attached to air pressure lines.

Surrounding the'tube 4 at one side of the ball is an annular flange 7 whereby the ball' 3 will be securely retained in position on the tube t and the other end of the tube can be slightly turned over toprevent the ball from being incidentally moved therefrom. In using the device, the ball 3 is-positioned in the mouth of the pipe bowl, as shown in- Figure 1, and the nipple 5 is then inserted into the ordinary type of check valve as shownat 6 and air under-pressure will then be admitted to the pipe bowl and due to the fact that the mouth ofthe bowl is sealed by the ball 3, theair under pressure will pass'through the pipe bowl; and onthrough the bore inthe SIBDTQp Byusing air under pressure, as il. lustrated-,:any particlesof tobacco, salivaand othermaterial in the bowlg as'well as in the bore of the stem will be quickly removed, leaving the bottom of the pipe bowl, as well as the bore of the stem comparatively dry and free from moisture.

In Figure 3, I have illustrated aslightly modified form of the invent-ion wherein the stopper member 8 is-of a semi-spherical form having the usual tube at extended therethrough, and provided with a nipple 5 for attachment to a check valve and the flange 7 which retains the stopper member 8 in position on the tube 4. In this form of the invention, the stopper member is also constructed of comparatlvely soft rubber, so as to positively seal the mouth of the pipe bowl when engaged therewith.

It is believed from the foregoing that I have provided a simple and inexpensive deviceof the character described which can be readily carried about in the pocket of a pipe user, so that when the user desires to cleanse the pipe of tobacco and saliva, which has become lodged in the bottom of the bowl, or the bore of the stem, the device can be quickly placed in position and readily connected up to a source of air under pressure for thoroughly cleaning and drying the pipe bowl and stem. This way of cleaning pipes is more eflicient and sanitary than with the use of the well known type of pipe cleaners where a wire is run through the stem of a pipe with a cleaning member attached thereto, as this type of cleaner does not thoroughly dry the bore of the stem during the cleaning operation. The method of blowing ones breath through the pipe stem is also objectionable, as it carries moisture into the stem instead of removing it.

However, by using my improved device and passing air under pressure through the pipe, it not only cleans it, but relieves the same of any moisture therein so that a cool dry smoke can be had after cleaning.

While I have shown and described the preferred embodiment of my invention, it will be apparent from the foregoing'that slight changes may be made in the construction when putting the invention into practice without departing from the spirit of the same or the scope of the appended claim.

I claim:

A cleaning device for smoking pipes comprising a tube having inner and outer portions, the outer portion being of greater diameter than the inner portion for connecting the tube with a pressure line check valve, said outer portion having an outstanding annular flange, and a soft rubber ball-shaped sealing head having a diametrically extending bore therethrough receiving the inner portion of the tube, said ball-shaped head being sprung on the tube against-said flange.

In testimony that I claim the foregoing I have hereunto set my hand at Colfax, in the county of Dunn and State of Wisconsin.
